Summary
| Description |
English: Solid line: A schematic of a typical Bloch wave in one dimension. (The actual wave is complex; this is the real part.) The dotted line is from the eik·r factor. The light circles represent atoms.
Español: En línea sólida: Un esbozo de una onda de Bloch típica en una dimensión. (La onda es, en realidad, compleja, y aquí sólo se muestra la parte real). En línea punteada: el factor eik·r. Los círculos suaves representan átomos. |
